Increasing the temperature of the system, will cause the equilibrium to shift toward the direction of the reaction that absorbs heat.
Answer: 5.48
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
Mathematically, pH = - log(H+)
where H+ represent the concentration of hydrogen ion
So, to get the pH of the solution with [H +] = 3.25×10-6 M:
Apply, pH = -log(H+)
pH = - log (3.25×10-6 M)
pH = - ( -5.48)
(Note that the minus signs will cancel out each other)
Therefore pH = 5.48
Now we know that the pH of the solution with hydrogen ion concentration of 3.25×10-6 M is 5.48 (i.e slightly acidic)
Thus, we can finally say 5.48 is the pH of the solution within a solution with pH = 4.50
B, but keep in mind the element sodium is very reactive (though table salts, on the other hand, are not).
Answer:
[H+] =5.62*10⁻¹⁰
Explanation:
pH = 9.25
The formula to find pH of a solution is
pH = -Log[H+]
9.25 = -Log[H+]
Take the anti log of both sides
[H+] = 10⁻⁹.²⁵
[H+] = 5.62*10⁻¹⁰
The concentration of Lithium Hydroxide is 5.62*10⁻¹⁰
